TO ALL WHOM IT MAY CONCERN:

Be it known that I, NORMAN W. WHEELER, of the city of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Lighted Ventilators, applicable to the decks of ships, the roofs of houses, and toother purposes; and I do hereby declare that the following is a. full and'exact description of the construction and operation thereof, reference being had to the accompanying drawings, with the letters of reference marked theron, forming a part of this specification, like letters indicating the same parts in the different figures, of which- Fignre l is a vertical section, and

Figure I? a plan of my improvement in lighted ventilators," while Figure 3 is a vertical section,

Figure 4 a plan, and

Figure 5 a sectional plan, showing one modification of my invention.

The essence of my invention consists in combining a glass top or light with any known Ventilating hood,v

cowl, or top, in such a manner that the ventilator will also serve to transmit light to the room or space ventilated; and also in a nieans of closing the hood or cowl, when desired, by swinging doors, which also serve as airdeectors, all as hereinafter described.

In figs. 1 and Q, a is a anged shaft, which may be secured permanently to the deck or roof over an aperture through the saine. B, the hood, fitted to turn around upon the shaft a, and guarded against leakage of faling water by the ringr and cape Z I. At the top of the hood B is fitted a frame, d d, within and to which is fitted one or more sheets or panes of glass C, which should be strong enough to resist any blows or shocks it will be likely to receive; and the frame should also be scuppered, as seen at jjjj, so that any water falling upon the glass C will reudil v run oli". At the upper part of the hood B is fitted a visor, l, projecting over the opening in the hood to prevent, in a great degree, the falling of water into the opening, and so down the shaft, and to afford means of scouring the d efiecting doors E E in the proper positions. The detiecting doors E E are hinged to the hood at M M in such a way that they may be swung in to close the aperture in the hood, and prevent the entrance of water completely, and also arrest the ventilation, which it would be necessary to do in cold and rainy weather; or thrown more or less open, and held in position by pins inserted in holes, as at z' t'. Atf is seen a. cross-bar secured to the hood B, to which cross-bar is attached the rod g, by which the hood may be turn'etl in any direction from below. At o is sccn a section of a hollow truncated cone secured to the shaft a, so formed as to catch what water muy have corne in and trickled down the inside of the hood, and run it out through small holes at K K. Figs. 3, 4, and represent a ventilator of ordinary construction, but fitted with a glass top, C, to render it :t lighted ventilator, the openings 21p, the., being covered against rain and spray by the shields R l, de., the draught in this case being always outward.

Having described my invention, I will indicate that which I consider new and useful, and for which I desire to secure Letters Patent: l

1. I claim the combination of the glass top C with the hood B, or their equivalents, substantially as described.

2. Iclnini the hinged deliecting doors E E, in combination with the hood B, provided with a glasstop, substantially as described.
